ROBERT P. BROWN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO BROWN &BAILEY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A PENNSYLVANIACORPORATION.

COLLAPSIBLE BOX.

To all whom it may concern:

Be it known that 1, ROBERT P. BROWN, a citizen of the United States,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania,

have invented certain Improvements in Collapsible Boxes, of which thefollowing is a specification.

This invention is a collapsible box adapted particularly for holdingclothing and so constructed that it can more readily be brought to theform desired and more securely held in the open position, avoiding theusual instability and being operated with greater facility than usualconstructions.

In the accompanying drawings, Figure 1 is a plan view of a blank ofsubstantially rectangular form, excepting the dovetail portion cut outof the end flap'7 to form the ears 13, cut and scored according to myinvention;' Fig. 2 is a plan view of the collapsed box made therefrom;Fig. 3 is a perspective view of the box in the open or operativeposition, and Fig. 4 is a vertical sectional view taken on the line 44ofFig. 3 showing an interior elevation of the end of the box.

The construction, designed for manufacture from.

paper board, comprises a blank with parallel longitudinal scoresl toform joints between the bottom 2 and the sides 3, the transverse scores4 to form joints between the bottom and the ends 5, the scores 6parallel to the scores 4 to form the infolding flaps 7, the through cuts8 in line with the scores 1 to detach the side extensions or flaps 9from the ends, the'diagonal scores 10 to permit the side extensions orflaps 9 to be folded along the score .lines and permanently secured bystaples or stitches 11 to the ends 5, the slots 12 in the sideextensions between the diagonal scores and the stitches, and the cars 13on the flaps 7 for engagement in the slots 12 to lock the infolded flapswhen infolded so that their edges 14 brace the sides 3, the flaps beingdetachably engaged so that distortion is not required in operating themand the edges preferably extending at least half the depth of the box toform broad abutments for the sides.

Specification of Letters Patent.

Application filed September 7,1906. Serial No. 333,594.

Patented July 23, 1907.

1 It wiil be observed that the side extensions forming the flaps 9project beyond the scores 6 to the outer line of the infolding flaps 7whereby there are provided when the flaps 9 are infolded as shown inFig. 2, a suitable construction for the engagement of such flaps to theends by the stitches 11 placed between the slots 12 so as not tointerfere with the engagement of the cars with such slots.

This construction will be seen to involve practically no waste materialand to provide a substantially flat structure with sides infolded whencollapsed, the box being readily opened or closed without distortion ofthe parts and firmly held in the operative position without the tendencyto knock down found in boxes having sides that fold outwardly or havinginwardly infolding sides without proper means for bracing them. 55.

Having described my invention, I claim'.

1. A collapsible box formed of a blank scored to provide sides and cndsand cut to form extensions of said sides, suchsidc oxtonsions hr-ingfolded alongdiagonal scores, moans securing said extensions to the boxends, such extensions having slots therein lwtwecn the diagonal scoresand the point of attachment to the box ends, said box ends beingprovided with infoldlng end flaps provided with ears to engage in theslots of the side extensions.

2. A collapsible box formed of a blank scored to provide sides and endsand cut to form extensions to said sides, such side extensions beingfolded along diagonal scores and having slots therein, and meansscouring said extensions to the box ends, said box ends being providedwith infolding end flaps having parts to engage in the slots of 79 theside extensions and secure said end flaps to said extensions.

In testimony whereof I have hereunto set my name this 5th day ofSeptember, (1906,) in the presence of the subscribing witnesses.

ROBERT P. BROWN.
